HarvesterLib
A C++20 library that processes log diameter and length measurements from timber harvesters.
The task
Raw harvester measurements contain artefacts and gaps. A reproducible pipeline was needed to turn them into clean data for analysis.
What we built
A four-stage pipeline; results are stored in SQLite and the intermediate steps remain available for analysis.
Parsing input files with unit conversion and artefact handling
Four-phase validation and cleaning
Alignment to a 10 mm grid
Extrapolation up to 50 mm
A local engineering dashboard for inspecting the stages
NDDev’s role
The work concerns the software and data of existing equipment. Hardware design and manufacturing were out of scope; accuracy on new data needs separate validation.
